What does this square bracket and parenthesis bracket notation mean [first1,last1)?

Are +0 and -0 the same?
... +0 = 0. However, in computing, some number representations allow for the em>x m>istence of two zeros, often denoted by −0 (negative zero) and +0 (positive zero). This occurs in some signed number representations for integers, and in most floating point number representations. The number 0 is usually e...

Why is it wrong to use std::auto_ptr with standard containers?
...y independent. std::auto_ptr does not fulfill this requirement.
Take for em>x m>ample this code:

vecm>X m>.push_back(new m>X m>);

To overcome this limitation, you should use the st...
Is there a Java equivalent to C#'s 'yield' keyword?
